* CAMERA-MAGAZINE.

To all whom t't may concemL Be it lmown that I, O'r'ro HERMANN Wnrcnnt,a sub-- ject of the Emperor of Germany, residing at Berlin, Germany,have invented a new and-useful Improvement in Camera-Magazines, of whichthe following is a specification. I I H i This invention relates to animproved magazine camera designed for three-color photographic work andhas for its object the provision of an improved magazine and alsoimproved plate holders therefor to gether with means for respectivelyinserting, retaining and releasing the plateholders when the magazine-isin use. i Y i The invention will be more fully described in connection.with theaccompanying' drawings and will be more. particularly pointedout in and by the appended claims.

In the drawings: Figure 1 is a vertical section'of a magazine embodyingthe main ieaturesof my invention in which there are arranged three plateholders, one behind the other, the forward plate holder being shown inan exposed position and the remaining plate holders being shown in anunexposed position. Fig.

- 2 is a similar view showing the second plate holder in an exposedposition and the third holder in an unexposed position. Fig. 3 is anenlarged sectional view illustrating a. combined releasing andretaining'device fdr the plate holders. Fig. 4 is a front'elevation of themagazine showing the plate holderain exposing posir ti'on's. Fig. 5 isa" detail sectional view of one form of pivotal mounting for the plateholders.

Like characters-of reference designate similar parts throughout thedifierent figures of the wings.

As shown the magazine comprises structure open at its forward. side andprovided at its forward margins with grooves adapted for engagement.with suitable devices wherebysaidmagazine may be removably. secured inplace to the camera in any de'-' sirable manner. The rear wall u of themagazine is adapted to be removed or opened to permit-insertion -of theplate holders and is preferably hinged to the upper wall of the magazineat 11/.- ,Magazine springs v are secured to the wall u in a manner toengage the plate holders at their rear sides and iorce the same into aforward position in the magazine. The side walls of the magazine areprovidedfwith superposed guiding channels a and f open at their rear andclosed at their iorward ends, said channel's extending rearwardly to thewalls u in a manner to be closed thereby. To one i of the side walls ofsaid magazinethere is pivotally v mounted a hail 2: provided "with acrankw for returning the plate holders from; an exposed to an unexposedposition.

rectangular ranged behind the other, the foremost plate holder beingprovided at one side with a trunnion 1 adapted to project into and beguided by .the lower channel a.

Patented Aug. 6, 1907.

At its opposite end said plate holder b is adapted to be]? engaged by ayieldingly acting pivotalmounting come posed of a plunger 4 seated'in asocket 2 adapted to be received in the lower channel a. Said plunger 4is,

held in engagement with the holder b by spring'3, said holder beingprovided with a recess 5 for theouter end of said plunger. By means ofthis construction the holder b may be easily removed and insertedand ismaintained against the opposite wall and. in a definite focal positionin the magazine. 'The socket Zandthe trunnion-1 engage the outerclosed'ends of the channel a and thereby the forward movement of saidholder 5 is limited. The next rearmost holder 9 is provided with pivotalmountings in all respects similar to the mountings of the first holder bwhich ,mountings are guided by thev channels f. The rearmost or thirdholder-q is likewise provided with mountings similar toholders b and .g,said mountings being guided by a. In order to enable the third holder qto be advanced in the magazine to the same focal exposing position .of

holders b and g, the said holder q, at itslower margin,

is oflset at in a manner to overhang the pivotal mountings of theholders b and g, when the latter are in exposing positions'as shown inFig. 2. It will be fur- H ther noted by reference to this figure thatthe pivotal mountings of the holders b and g which have engaged theforward closed walls of the channels a and f form stops limitingtheiorward movement of the lower end oi the holder q; Each of theholders b, g and q is pro vided with means for supporting" andretainingthe plates i'n position which means, asshowri, consists ofoppositely disposed guides c, h and r, andinterposed plate engagingsprings d, t and s. Said guidesand springs are arranged upon the holdersin: parallel relation] in .a manner to permit the platesto be insertedand withdrawn laterally. In orderto automatically advance the holdersafter they have been released so that they will fall by gravity intoa-lowerior exposed 'vided for releasing holders 1) and g, one at a time,and

position, each of the plates 9 and q is provided with for retainingtheholder q. vAs shown, said devicelis L located in the'upper wall ofsaid magazine in a manner to engage the margins ofthe plate holders atpoints opposite to their pivotal engagement with the channels a and f.In the form shown, said device consists of a retaining lever m. pivotedat m and provided with a retaining extension} adapted to project throughthe upper wall of the magazine'into engaging proximity with the plateholder's. Said lever is held in a retaining position by means of aspring m secured at one end to any convenient stationary part andbearing at its free end upon said lever m. At its opposite end saidlever m is apertured and is adapted to be engaged by ashoulder 2 formedupon a plunger 2 upon the upperend of which is mounted a bearing platep. The lower reduced end Z2 of said'plunger projects through the lever.

gages said lever y and normally holds the same in a retracted position.'A bearing plate 0 secured to the upperwall of the magazine overhangsthe bearing plate 1) and there is interposed between said plates anexpansion bulb n operated by means of ag tube n and a compression bulb nllt will be obvious, however, that the device may be operated manually.

The operation is as follows: When it is desired to load the magazine therear wall it is opened and the plate holders are inserted in theirrespective guide channels. When the wall 21. is closed the springs'rwill engage the rearmost plate holder and acting therethrough willadvance all of the holders to a forward position at which point theforemost holder is engaged at its upper margin by the retainingextension Z and at its lower margin by the closed forward end of thechannel a. The'bail at will next be thrown downwardly into the positionshown in Figs. 1 and 2. The holder b is now in an exposing positionandafter the exposure is made the operator will compress the bulb 'n.expanding the bulb n and forcing the plunger z downwardly. Thisoperation serves to lift the extension I to release holder b andsinultaneously throws the projection y into engagingposition with thenext rearmost holder 9. When theextension Z is retracted to free theholder b the spring is will thrust the holder b forwardly at its upperend causing the latter to descend by gravity upon its pivotal mountingto the position shown in Fig. 1'. Assuming now that pressure on the bulbn has been released the plunger 2 will be restored to its normalposition by the action of springs 1n and y thereby serving to lift theprojection y out of engagement with the plate 9 and forcing theextension Lin-the path ofsaid plate. When said plate hasbeen released bythe stop'projection 3 the springs 5 1) will advance the plates q and gforwardly to the positiori shown in. Fig. 1. After the plate in holder 9has been exposed the bulb n will be compressed and the same operationwill'release andadvance the plate 9 on its pivotal mounting and will'force the plate holder q into an exposing position as shown in Fig. 2.v When all of the plates have been exposed the operator will return theholders b and g-by means of the bail x. 1
